  最近项目在 IE 11 下 点击出现 “__doPostBack”未定义”,经过一番google,终于知道了原因:ASP.NET 可能无法辨识出一些浏览器的最新版本,还会经常把它们看做是低级的浏览器。(也就是: 不支持JavaScript。)

详见: http://blogs.msdn.com/b/scott_hanselman/archive/2011/10/28/asp-net-ie10-dopostback-javascript-ff5.aspx
本人按照该文所提供的解决办法始终未能得到解决,于是按提示尝试用单个站点的方式修复。
在项目根目录 App_Browsers 下新建 浏览器文件(.browser),让其与IE11的 UserAgent 匹配,使 .net framework 认识这是一个已知的浏览器,可以正常地向客户端输出脚本。

在文件里输入以下内容,保存即可。

  "IE11" parentID="Mozilla">
    
      "Trident\/7.0; rv:(?‘version‘(?‘major‘\d+)(\.(?‘minor‘\d+)?)(?‘letters‘\w*))(?‘extra‘[^)]*)" />
      "IEMobile" />
    
    
      "Trident/(?‘layoutVersion‘\d+)" />
    
    
      "browser"              value="IE" />
      "layoutEngine"         value="Trident" />
      "layoutEngineVersion"  value="${layoutVersion}" />
      "extra"                value="${extra}" />
      "isColor"              value="true" />
      "letters"              value="${letters}" />
      "majorversion"         value="${major}" />
      "minorversion"         value="${minor}" />
      "screenBitDepth"       value="8" />
      "type"                 value="IE${major}" />
      "version"              value="${version}" />
    
  
 
  
  "IE110" parentID="IE11">
    
      "majorversion" match="11" />
    
 
    
      "ecmascriptversion"    value="3.0" />
      "jscriptversion"       value="5.6" />
      "javascript"           value="true" />
      "javascriptversion"    value="1.5" />
      "msdomversion"         value="${majorversion}.${minorversion}" />
      "w3cdomversion"        value="1.0" />
      "ExchangeOmaSupported" value="true" />
      "activexcontrols"      value="true" />
      "backgroundsounds"     value="true" />
      "cookies"              value="true" />
      "frames"               value="true" />
      "javaapplets"          value="true" />
      "supportsCallback"     value="true" />
      "supportsFileUpload"   value="true" />
      "supportsMultilineTextBoxDisplay" value="true" />
      "supportsMaintainScrollPositionOnPostback" value="true" />
      "supportsVCard"        value="true" />
      "supportsXmlHttp"      value="true" />
      "tables"               value="true" />
      "supportsAccessKeyAttribute"    value="true" />
      "tagwriter"            value="System.Web.UI.HtmlTextWriter" />
      "vbscript"             value="true" />
    
  

 

 

自己在项目中添加的文件:

"IE11" parentID="Mozilla">
        "Trident\/7.0; rv:(?‘version‘(?‘major‘\d+)(\.(?‘minor‘\d+)?)(?‘letters‘\w*))(?‘extra‘[^)]*)" />
          "IEMobile" />
        "Trident/(?‘layoutVersion‘\d+)" />
        "browser"              value="IE" />
          "layoutEngine"         value="Trident" />
